This code uses the useState() hook to construct a counter component that maintains its own state. The increment() method we defined changes the state when the user clicks the increment button. ReactJS automatically refreshes the user interface (UI) to reflect state changes.

2. Integration With Other Frameworks and Libraries

Redux, GraphQL, and React Router are tools and frameworks that ReactJS integrates well with. This enables programmers to combine the strength of various technologies to produce more sophisticated applications. The following piece of code demonstrates how to use React Redux with ReactJS:

import { createStore } from 'redux';
import { Provider } from 'react-redux';

const store = createStore(reducer);

ReactDOM.render(
  <Provider store={store}>
    <App />
  </Provider>,
  document.getElementById('root')
);

3. Single-Way Data Flow

Data travels exclusively in one direction, from parent components to their child components, according to ReactJS’s unidirectional data flow model. This makes it simpler to maintain the application’s state and stays clear of traps like spaghetti code and race situations. The usage of a parent component to control the state of its child components is illustrated by the following piece of code:

function Parent() {
  const [count, setCount] = useState(0);
  function handleIncrement() {
    setCount(count + 1);
  }
  return (
    <div>
      <Child count={count} onIncrement={handleIncrement} />
    </div>
  );
}
function Child(props) {
  return (
    <div>
      <h1>Count: {props.count}</h1>
      <button onClick={props.onIncrement}>Increment</button>
    </div>
  );
}

4. Better User Experience With Server-Side Rendering (SSR)

ReactJS supports server-side rendering, which results in quicker website loads and improved SEO. ReactJS server-side rendering is demonstrated using the following piece of code:

const express = require('express');
const React = require('react');
const ReactDOMServer = require('react-dom/server');
const App = require('./App');

const app = express();
app.get('/', (req, res) => {
  const html = ReactDOMServer.renderToString(<App />);
  res.send(html);
});
app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

We create an Express route for the root URL (/) in this example. At the point when this course is mentioned, we get the underlying information from a Programming interface and pass it as a prop to our Respond Application part. We then, at that point, utilize the renderToString capability from respond dom/server to deliver the part to HTML.

5. Binding of One-Way Data

The user interface is automatically updated when a component’s state changes in ReactJS. As a result, complicated two-way data binding is not required, and it is simpler to maintain the application’s state. The following piece of code demonstrates one-way data binding with ReactJS:

function Counter() {
  const [count, setCount] = useState(0);
  function handleIncrement() {
    setCount(count + 1);
  }
  return (
    <div>
      <h1>Count: {count}</h1>
      <button onClick={handleIncrement}>Increment</button>
    </div>
  );
}

6. Syntax in JSX

Using JSX, developers may construct reusable components that separate UI and logic concerns. It enables programmers to write clear and readable code, which saves time and effort when creating complex UI components.

ReactJS is the best choice for front-end web development because of the JSX syntax. Programmers can manage and create user interfaces using HTML-like syntax thanks to the JavaScript extension JSX.

Additionally, JSX enables programmers to swiftly include dynamic content into HTML-like code by using JavaScript expressions.

const title = "Paul";
const element = <h01>Welcome, {title}!</h01>;

Developers may make their reusable UI components thanks to JSX’s support for custom components. In this case, the name of the variable created will be inserted dynamically into the HTML-like code using the JSX syntax.

Due to this ReactJS feature, you can create dynamic UI elements that can be used across the program to make it simple. With the use of this functionality, it makes it simple to create intricate UI components with clear and intelligible code.

7. React Native Cross-Platform Mobile Development

With React Native, JavaScript code can be compiled into native code for the iOS and Android platforms by developers. Using the FlatList component and some custom styles defined with the StyleSheet API, you can build a mobile app that displays a list of items retrieved from an API. The react-native command-line interface can be utilized to compile the application for both platforms.

You can create cross-platform mobile applications on Android or iOS using this feature of ReactJS together with React Native. This will allow you as a developer to use existing ReactJS knowledge in building mobile apps.

8. Simplified UI Testing

Using Simplified UI Testing in ReactJS (React Component Libraries), developers can test user interfaces and guarantee that they operate as planned. Compared to traditional DOM-based testing, ReactJS’s virtual DOM allows them to develop more declarative and efficient UI tests. We’ve shown some React component libraries that help with accessibility, for example.

They may create automated tests that imitate user interactions and validate the UI response, making it simpler to identify flaws and failures before they reach production. As a consequence, the web application is more stable and trustworthy.

import React from 'react';

import { render, screen } from '@testing-library/react';
import Greet from './Greet';
test('renders a greet', () => {
 renderf(<Greet by name="Hello" />);
 const greetElement = scren.getByText(/hello, world/i);
 expect(greetElement).toBeInTheDoc();
});

9. Integration With Other Frameworks and Libraries

The interaction of ReactJS with other frameworks and plugins is primarily responsible for its prevalence as the go-to solution for front-end web development. By mixing ReactJS with other frameworks, such as Angular or Vue, developers may use each framework’s unique characteristics while using ReactJS’s strengths.

Developers, for example, may use Angular’s sophisticated dependency injection architecture alongside React’s reusable components and virtual DOM (see pros and cons of React’s styled components for more info). Developers may profit from Vue’s reactive dynamics in the same way that they can benefit from React’s component-based architecture by integrating React and Vue.

Furthermore, ReactJS has a large library of pre-built components, including the well-known Material UI toolkit, making it easier for developers to create responsive and appealing user experiences. ReactJS is also compatible with popular state management technologies such as Redux and MobX, making complicated application states simple to handle.

10. Using Hooks

Hooks, introduced in ReactJS 16.8, provide a more easy way of handling state and lifecycle activities in functional components. As a result, it is easier to create and manage components, and class components are no longer required. The following code demonstrates how to use hooks in a React component:

import React, { useState } from 'react'
function Counter() {
 const [count, setCount]}

ReactJS provides powerful features and tools that enable developers to create dynamic, interactive user experiences. Given its widespread use and continued development, ReactJS should remain the front-end web development framework of choice for the foreseeable future.
